DUMP-WAGON BODY.

To aZZ whom t may concern.'

Be it known that we, WALTER L. GOODWIN and Amr. HoLMAN, citizensof theUnited States, residing at Seattle, in the county of King and State ofWashington, have invented a certain new and useful Improvement inDump-l/Vagon Bodies, of which the following is a specification.

Our invention relates to improvements in dump-wagon bodies and theobject of our invention is to provide a dump-wagon body in associationlwith the running gear of a vehicle, as an auto-truck, which dumpwagonbody shall be specially adapted to serve in the operation oftransporting gran ular material,l as, 'for instance, sand or gravel todump said material at a desired point or to distribute said material onthe path of said vehicle during its travel; and which shall be of suchparticular plan of construction that several of its parts may beseparated and reassembled in the operation of repairing or renewing saidparts.

We -accomplish this object by devices illustratedin the accompanyingdrawings wherein Figure 1 is a view in side elevation of vone form of astructure embodying our invention; Fig. 2 is a view of the same incross-section on broken line a', of Fig. 1; Fig. 3 is a fragmentary viewof the same in longitudinal section on broken line y, y of Fig. 2; andFig. 4 is a perspective view of one of the slats.

Referring to the drawings throughout which like reference numeralsdesignate like parts, upon the running gear of a vehicle, represented bywheels 5, axles 6 andA supports 7, is mounted a body which includesoppositely disposed side rails 8 and 9 of channel iron, which side rails8 and 9 are re-inforced by wooden rails 10 and 11, respectively, whichare disposed to iit tightly within the oppositely facing channels ofsaid side rails 8 and 9 on the top surfaces of which are disposed, toextend lengthwise thereof7 bearing bars 12 and 13 and bearing bars 14and 15, respectively, and on the top surfaces of the bearing bars 12 and14 are disposed side walls 16 and 17, respectively, which are fastenedby bolts, as bolts 18, which extend downwardly through the bearing bars12 and 13 and side rail 8 on one side of said body, and through bearingbars 14 and 15 and side rail 9 on the other side thereof.

The side .rails 8 and 9 are rigidly con- Specication of Letters Patent.

nectedby a frontend rail 19 and a rear endk rail, indicated by dottedline 20, to form a rectangular body frame, and the side wall 16 and 17are connected by a front end wall 21 and rear end wall indicated bydotted line 22 which end walls 21y and 22 extend therebetween.

At equi-distant points. in bearings, like.

bearings 23 of Fig. 3, formed between the bearing bars 12 and 13and atcorrespondingv opposite points between the bearing bars 14 and 15, aredisposed to be rotatively movl able a plurality of shafts 24, eachprovided on its opposite end portion, with journals 25 and 26 and with asquared portion 27 adv Patented Aug. 20,1918".- Application1ed-November20, 1916. Y Serial No. 132,475, I Y l Y i' jacent to itsjournal 25 together with a screw-threaded portion 28 adjacent to saidsquared portion 27, as shown more clearly in Fig. 4, and that portion ofit lbetween said journals 25 and 26 is of rectangular form in crosssection.

Securely fastened to eachof said shafts Y 24 by rivets, as rivets 29, isa metal Slat, 30, which extends thereon throughout the distance betweenthe journals 25 and 26, and

which is so disposed vthereon that when the several shafts 24 areVmounted in their respective bearings, 'as shown in Fig. l, then theforward edge portion of each of said slats 30 shall lap over therearward edge portion of. an adjacent oneVl thereof when' all of saidshafts 24 shall have been turned to the position indicated inpFig. 3whereby said slats 30, so long Aas they are maintained in such position,shall form a iioor upon which may be deposited sand, gravel and otherlike earthy material that is to be transported within said body; butwhen all of said shafts 24 are rotatively moved to dispose theseveral'slats 30 in the position Y V3), and articulated to the upper endportion of all of said arms 31 is a connecting rod 32 whose forward endportion is articulated to a hand lever 33 that is ladapted in a wellknown manner to be actuated to communicate endwise movements to theconnecting rod 32 toswing thear'ms 31 to dispose and maintain the slats30 in their open positions shown by dotted lines in Fig. 3, or at anydesired angular positions between their open and closed positions, saidYhand lever 33 being provided with a detent mechanism 34 that is adaptedto engage with a notched segment 35 that may be'secured to sui-tablelwithin said body to be supported bythe closed slats 30` of said floorduring the travel of the vehicle to the point of deposit of its load, atwhich point the hand lever 33 is moved rearwardly to dispose the slats30 in their position shown by dotted 'lines iii-Fig. 3, thus to permitsaid granular material to fall through the spaces between adjacent onesof the several slats 30 thereby to' unload said material and thereuponthe hand lever 33 may be again disposed in its forwardmost position toclose the slats 30 4for another load of material.

If it be desiredto distribute material con tained within the body overthe path of the vehicle while said vehicle is moving thereover, thenthehand lever 33 maybe moved to *such position that its detent mechanismCpi'es of,- this patent' may be vobtained. for

34 may engage with such one of the notches of the notched segment 35 aswillvcause the slats 30 to be disposed Vvat suchangle as will permitsaid material to pass downwardly between adjacent ones of them at adesired rate of flow.

If it be requiredto repair one or more of the slats 30' or the shafts 24connected therewith such parts may be quickly removed froin thestructure by disconnecting the connecting rod 32 and removing the bolts18, whereupon the side walls 16 and 17 and the bearing bars 12 and 14may be raised and dismounted thus to permit such removal in anl obviousmanner.

Vlwanife'stly, changes may be made in the forms and dimensions of partsof our in-V vention' without departing from the spirit thereof.

VVha't we claim is:

In a dump wagon a frame, channel membersV receiving the side members ofthe frame, bars superposed upon the channel members, a body having atits sides outstanding langes, which rests upon the upper bars, securingdevices passing transversely through the flanges, bans, channel membersand side members of the frame, shafts ournaled between the bars, meansfor turning the shafts simultaneously and slats carried b ythe shaftsand adapted to overlap each ot ier.

In witness whereof, we hereunto subscribe our names this 15th day ofNovember,
